To all whom (it may concern:

Be it known that 1, Greece LEONARD Gon'rz, a citizen of ,t e UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inBooklet-Covers, of which the following is a spec' cation.

The object of the present invention is to provide a. cover device whichmay be previouslyprepared incomplete form and will be self applying to aflat-opening multiple pagebooklet insert, and adapted to hold the latterin position with the individual leaves free tohinge upon a single axiswhich substantially coincident with the hinging axis of the covers andWithout obscuring any of the reading surface on the exterior pages ofthe insert; and the invention consists" essentially in a cover devicecomprising a pair of covers suitably related to hinge one upon theother, and carrying a binding attachment comprising a single strip ofmaterial having along its medial line a single line hinging connection,with the covers in ooincidence with the hinge of the covers and in amanner to present, on opposite sides of the hinge line, a pair of"integral free margins providing a space sntlicient to admit the insertto be held, with the inner edges of its pages upon which they hingesubstantially coincident with the hingi'ng axes of the bindingattachment and cover, and with an adhesive on the opposed faces of themargins of thebinding attachment in position to develop adhesion alongthe outer faces of the inner margin of the insert without obscuring anyof the reading area of the outer faces of'the latter. 7

The present invention, which afl 'ordsan effective means for realizingthese results, consists essentially in a cover device comprising a pairof covers suitably related so that they will hinge one upon the other,and a combined binding and gathering. attachment secured along itsmiddle line to the fold line ofithe covers so as to make a single lineattachment thereto and presenting narrow free edges for receiving andadhering to the aok marginal portions of the two outer pages of theinsert to be bound, and leaving a space between said freeedges forreceiving and holding said insert in a manner to leave its several pagesfree to be turned upon a single line aids approximately coincident \vthfhe single line hinging axis of the binding attachment, and therebyadapted to be individually displayed like the leaves of a book.

The invention will be fully understood upon referring to theaccompanying drawings, in yvhieh- ,Figure 1 is a perspective view of acover device embodying the features of the pres out invention, theadhesive applied to the frec edges of the bindingand gatheringattachment being uponthe inner opposed faces thereof;

Fig. 2 is a similar view in which two bindand gathering attachments areused, the hesive being ap lied to the opposing faces of thebinding angathering attachments;

Fig. 3 is a perspective view illustrating the device of Fig. 1 with aninsert applied in the manner to leave a plurality of intervening leaves;

1 shows the device of Fig. 3 folded or closed;

Fig. 5 is a. perspective view showing the device of .Fig. 1 with another,form of folder therein;

Fig. 6 shows the arrangement of Fig. 5 in open or full display position;and

Fig. 7 is a view showing a folder of a somewhat different form attachedto the cover device of Fig. 2 and with the series of folds secured atone end only so as to adapt it to open out as a continuous strip, Fig. 8showing the same open.

'1 represents the cover device, consisting of a pairof covers hingedtogether so that they may fold one upon the other upon opposite side'sofa filler or insert to which they are to be applied. This cover devicehas permanently attached to it a binding and gathering attachment 2,which is secured along its middle line to the folding line of the coverdevice, as, for instance, by staples 3 or sewing, stitching, or othersecuring means, in a 111a11ner to provide a single line hingingaitzufilnncnt and leave its edges 1 free, with a gathering space 5between them; a suitable adhesive (5 being provided on these free edgesto adapt them for self-attachment to the outer faces, folds or leaves ofan insert or filler to be covered. The adhesive (5 may be upon the inneropposed faces of the attaclnnent :2, as shown in Fig. 1, or it may beupon the opposing faces of two binding and gathering attachments, assuggested in Fig. 2.

One method of using the cover device is suggested in Fig. 3, wherein 7represents a sheet folded backward and forward upon itself after themanner of an accordeon fold for the purpose of providing leaves 7*, eachfree to hinge upon the single line of its inner edge as an axis; theinsert thus provided being secured to the cover device in position tobring the single line swinging axes of the leaves approximatelycoincident with the line of stapling of the attaching strip, as, forinstance, by moistening the adhesive upon the free edges of theattachment and UtlllSlng the same to adhere to the back edges of the twooutside leaves of the insert; both free edges of the attachment beingcaused to adhere, as shown in Fig. 3, and the intermediate folds whichare not attached being gathered and confined in the space 5. If theinsert 7 be made of a sheet whose dimension from top to bottom is twicethe length of one of the leaves, and folded first to half its verticaldimension before being folded to produce the leaves, the result will beto make, in each leaf, pockets 8 which will serve conveniently for thereception of a sample 9, and if the material of the insert betransparent paper. obviously the sample may be inspected withoutremoving it from the pocket, and, therefore, with minimum wear and tearupon the same.

As suggested in Fig. 4, the device of Fig. 3 may be closed up forconvenient handling and shipment, and when so closed presents the neatappearance of a book, and affords ample face upon the cover device forthe advertisement of the distributer or such other matter of informationwhich it may be desired to display in addition to that presented by theinsert.

If the inserted device as described in Fig. 3 is such as to present buttwo leaves, as suggested in Fig.5, it is obvious that when the coverdevice is opened out flat and the two leaves are oppositely extended thesheet may be unfolded in the direction of its length, and thus presenton the inner face, as suggested in Fig. 6, a large and ample sheet uponwhich to print an advertisement in simulation of a personal letter orany other nfitter that a large sheet would render availa 1 e. 4

As shown in Fig. 7, the insert may be at tached by one only of its endfolds, leaving the other end fold free so that any desired number of itsfolds may be extended even to the full extent of the sheet, and thepurpose of the invention will be realized, measurably at least and tothe extent that the combined binding and gathering attachment serves asthe means for retaining the insert, gathering or confining it betweenthe free edges, and serving as a cover device therefor. lVith one edgeonly of the insert attached, as suggested in Fig. 7, the insert may beof the character shown in Fig. 3 with a plu rality of 2-ply folds, theplies of which are united at one end by the original longitudinalfolding of the sheet, and thus the insert of Fig. 7 when the folds arecompletely ex tended could be opened out still farther by unfoldinglongitudinally, as shown in Fig. 8. For instance, so long as the linesof adhesive are near the hinge line, tliey will leave the outer faces ofthe attached folds or sheets free from obstruction even though the attaching strip may extend out ardly beyond the adhesive line.

The foregoing will be sufficient to illustrate the uses to which myinvention may be put. Obviously, these uses may be multiplied withoutdeparting from the spirit of the invention.
